FRICTION SUPPORTING MEANS FOR SCREENS AND STORM SASHES Filed Feb. 24. 1 30 Wllfdf Patented May 17, 1932 P ENT-OF IC FRIGTIONSUPPORTIN 'G MEANS FOR SCREENS AND STORM SASHES Application filed February 24, 1930. Serial No. 430,576.

This invention relates to that type of auxiliary closure members such as screens and storm sash designed to be formed in two units and to be employed in a double sash I '15 Window, frame in association with vertically arranged supporting barscarried by the side members of thewindow frame in such manner thatthe auxiliary closure members may be removed and; replaced from within a building.

j The particular object of this invention is to provide a friction holding means associated withthe supporting bars for engaglng one of the units of the auxiliary closure means it 5 for holding it in position while the other unit is being removedand replaced, and also for affording a close engagement of the closure unit with the supporting bars.

Another object of the invention is to provide an improved resilient means for frictionally engaging the side members of the closure unit, such as a screen or storm sash frame, for yieldingly holding the unit in the desired position and at the same time causing an intimate contact of the unit with permanently mounted supporting members.

VWith these. and other objects in View my invention consists in the construction, arrangement 'and combination of the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set'forth, pointed out in my claims, and illustrated in the accompanying drawings, in"

which: l j

Figure 1 is a vertical sectional view of a window frame equipped with my improved friction holding devices which are here shown in engagement with the upper unit of a storm sash. j V

Figure 2 is a transverse vertical section of j the same on the line 22 of Figure 1.

Figure 3 is a detailed horizontal view on the line 3 3 of Figure 1; and

Figure 4 is a perspective view showing a portion of one of the supporting bars with the improved friction holding means applied thereto.

The subject matter of the present application was shown and described-in part in my "companion application filed September 24th,

1928, Serial Number 307,841.

In the accompanying drawings I have used the numeral 10 to' designate the sill of an,

ordinary double sash window frame, which frame also includesside casing members 12, a head casing 14, side blind] stops 16 and a head blind stop 18.

Within the window frame thus formed are designed tobe mounted auxiliary closure members such as screens or storm sash which are formed in two units designated by the characters A and B. i i

To assist in mounting the I employ a'pair of supporting bars 0, one of which is mounted in vertical position on eachof the side casings 12 and extending from the sill 10 to the head casing 14. Each body portion 20 formed with'an attaching 'flange'22 which is' adapted to besecured to a side casing 12 immediately outside of a side blind stop 16. The body portion 20- of each supporting bar extends inwardly to ward the median line of the window frame past the plane of the innermost margin'of the blind stop 16 and terminates in a channel track portion 24 which faces inwardly toward the interior of the building.

Each of the closure units A and B includes a side frame member or stile'26 which is units A and B.

of the supporting bars C is composed of a within a channeled track portion 24 of one of the supporting bars.

My improved friction supportingmeans forming the subject matter of the present application is particularly designed for engaging thestiles 26 of the upper unit A for holding said unit in close engagement with the upper parts of the respective supporting bars C and with the flanges 28 engaging within the track portions 24. i

The friction holding means is composed primarily of a plate 30 formed of sheet metal and having at one margin a laterally directed attaching flange32 which overlaps the attaching flange 22 of one of the supporting bars G. The attaching flange 32 is rigidly gages the innermost flange of the track portion as shownin Figure 4. p i

The friction supporting plates 30 preferably are of somewhat less length than the vertical dimension of the upper closure unit A and "extend substantially from the head casing 14 to a position somewhat above the I position which is normally occupied by the lower margin of the unit A when in position.

preferably is formed with a longitudinal rib or bead 36 for the purposeof lending strength and-rigidity, and tatits lower inner corner the plateis bent and shaped to form'a lip 38 which is=directed toward the interior of the building. g

The closure units A and B may be removed and replaced byopening the lower sash of the window. The upper unit A is first placed in position by causing its stiles 26 to engage the lower parts of the supporting bars C and then sliding the unit upwardly with the -flanges28 in the channel portions 24, until 3 the stiles 26 engageand pass between the [friction plates 30 and the supporting bars. .The passage of the stiles 26 behind the friction plates 30 is facilitated by the rearwardly turnedlips 38' and the friction plates yield sufliciently to permit the stiles to pass'into the proper position as clearlyshown in Figure3. A

The unit A is moved upwardly untilthe upper margin engages the head casing 14 and its upper marginalportion preferably passes behind a transversely arranged strip 40 carried by said 'head casin'g in a position spaced inwardly somewhat from the upper ends of the supportingbars C. V

The tension exerted by the friction holdingplates 30 is sufficient to hold the upper unit A in place until such time as the lower unit is mo'unted beneath it and such tension 'also serves to produce 'a tight fit of the unit A against the supporting bars and to prevent vibration and rattling.

If desired, the inherent resilience of the "friction plates '30 may be supplemented by 44carried by the plate 30 and project loosely through bracket members 46 spaced in-- backing springs 42 which are coiledon studs wardly from the plates. The brackets 46 may be formed at their ends with attaching flanges or earsv 48 overlying the flanges 32 The free margin of the friction plate 30' 7 member.

of the friction plates and held in place by the rivets 34.

After the upperunit A has been placed in position the lower unit B may be placed.

against the lower portions of the supporting bars C and held by suitable means, such as .pivotedlatches 50 carried by the Supporting bars. The lower margin of the unit B may be caused to engage behind stops 52 located.

adjacent the sill 10 and the upper marginal portion of the unit B may be provided with a flange 54 overlapping the lower railof the'unit A, thus producing a tight joint between thetwo units.

The resiliently mounted friction holding plates 30 provide economical, convenient and eflicient means for automatically gripping and securely holding the upper unit A in such manner that said unit may be easily andquickly removed and replaced by a sim ple vertical sliding movement relative to the supporting bars G.

The princlpal parts of this structure, including the frames of the'auxiliary closure units, whether screens or storm sash, and;

alsoincl-uding the supportingbars and the friction holding plates maybe made ofsheet metal by stamping and thus a" cheap, durable structure is provided. vFurthermore the parts are not bulky and are thus easily hall-'1 dled and stored and they present a pleasing p appearance when mounted on a building- 7 Some changes may be made'in the construction and arrangement of the parts of my device without departing from the real spirit and purpose of my invention, and it is my intention to cover by myclaims, any modified forms of structure or use of mechanicalequivalents, which may beireasonably included within their scope;

I claim as my invention r e p 1. Friction supporting means for 'a window closure unit, comprising a. rigidly mounted supporting member, afriction plate arranged parallel therewith, a bracket substantially parallel with and spaced from the plate, a stud carried by the plate and. extending loosely through the bracket, and a tension spring coiled on said stud for causing the plate to exert yielding pressure on a-unit mounted between itselfand the supporting 2.
